Throughout my life I've always MECHANICALLY (NOT cosmetically) "improved" my vehicles to a great degree. In 2005 an old full-size American car ran into & totaled my Lotus. In the payout I asked the insurance agent if I'd be compensated for said improvements. He said, "sure, just show us the receipts." However when I handed him receipts for parts alone totaling $16,000 he, for 'some' reason, changed his mind about reimbursing me!!!

Anyway, except for reliability related changes like sticky key & re-soldering the RCM I've left the Crossfire entirely stock, proving that even old dogs can change!
